4 Claims.

Another object of the invention is to provide a curler of this type Which shall eliminate the usual pivoted band, so that it will notI be necessary tol close such a band on the curler When the hair has been Wound upon the device. Like- Wise, .after the curl has been set, vthe curl can be removed from the curler by a longitudinal sliding movement.

Another` object is to provide a device which can be easily manufactured and assembled and in which the hair Will not be caught in the clamp or in the external bar.

Other objects Will be stated in the annexed description and drawings which illustrate preferred embodiments thereof, it being understood that the above statement of the objects of my invention is intended generally to explain the same Without limiting it in any manner.

Fig. 1 is a section, partially in elevation, on the line I-I of Fig. 2.

Fig. 2 is a top plan View of the improved third embodiment of the invention.

Fig. 7 is a side elevation showing the holding bar of Fig. 6.

Fig. 8 is a sectional View on the line 8 8 -of Fig. 6.

The device illustrated in Figs. 1-4 has a tubular or tapered hollow body I, Which can be made of aluminum or other suitable metal. A clamping bar I0 is connected to lugs of the body I, by means of a pivot pin II. The usual torsion spring I2 holds the clamping bar I0 in its operative position. In said position the end of the clamping bar I3 abuts the body I. `This clamping bar I0 is of concave-convex crosssection so that only the longitudinal edges of said clamping bar I0 contact With the outer periphery of the body I.

A holding member or holding bar has an inner shank 5 and an outer shank 4. This holding member is preferably made of aluminum Fig. 6 is a view similar to Fig. Lshowing a 1939, Serial No. 260,50?

or of an aluminum alloy Vand it is exible and resilient. VIt has the normal shape shown in Fig. -1, in which the free tip Aof the outer curved shank 4 either abuts 'or is very close to the periphery of the tube I. The inner shank 5 5 passes loosely through a longitudinal bore ofv a cap 2. vThis cap 2 has atight. t upon the adjacent end of the body I. Said cap has a lateral end-Wall which, in effect, is a. lateral end-Wall of the mand-rel and its bore serves as a bearingv for vthe shank 5. The inner shank 5 is longitudinally movable relative to the cap 2 andithe member 5I. The friction or tight t of Ithe cap 2 on the member I is suiicient to retain these elements in assembled position, although they can be detached by using suitable force. A -collar'a having -a flange 6, is fixed to the Sinner shank 5. A compression spring 'I has -one end abutting the flange 6. The lother end of the compression spring I abuts a Washer 8 which can -be made of `brass or otherv `metal which harder than aluminum. The Washer -8 serves `as an abutment washer to take up the thrust of the spring -'I. The shank 5 can be inserted through ythe bore of the cap 2, and the Washer 8 and spring "I and the collar vIia can then be mounted on the shank 5, and the collar 5a is then xed to the shank 5 in any suitable manner. 'The shank 5 can then be inserted through the member I. The parts can thus be very easily assembled. A `ferrule 3 has a -tight fit upon the shank 5. This errule 3 has -an inner bearing portion 3a which ts closely but turnably in the mem-ber I. Saidr ferrule 3 has a knurled end portion. Said ferrule 3 Vcan be slidably vassembled with shank 5, after said shank has been pushed through tube I. A tight-or drive fit is sufcient to assemble members 3 yand l5.

When the parts are thus assembled, the ferrule 3 can be held Xed by one hand of the operator as shown in Fig. 4, and the tube I can be Ytur-ned freely relative to the ferrule 3. The holding member fi, v5 is Aalso 'held fixed relative to the member fl and the head 2, when. the ferrule .3 is held in .one hand of the operator.

The .member I'has a ycut-out portion which the linger-piece 9 of `,the .clamping bar Il] enters when the clamping bar-I0 is :moved to lthe inoperative position. .This Aprevents vthe :hair `from catching :between the linger-piece :9 Jfand Vthe member I.

In order Ato use this device, :the finger-.piece 9 :is pressed inwardly and :the end .of fthe lock of hair islocated between the clamping bar lllof the member I. The nger-piece 9 is then released and the spring I2 turns the clamping bar I0 around the pivot pin II, so as to clamp the end of the lock of hair between the clamping bar ID and the member I.

The operator then holds the head 2 in one hand, and the ferrule 3 in the other hand. The head 2 is then turned in unison with the member I and the clamping bar I0, while the ferrule 3 and the member 4, 5 are held against turning. The strand of hair is thus wound spirally or helically around the body I and the clamping bar IU. The spring 'I forces the washer 8 against the head 2 with sufficient friction So as to prevent the member I from turning backwards, when the device is released.

The device is allowed to remainon the lock of hair H until the lock of hair has dried and set into curled form. The clamp I0 is then moved slightly away from its operative position so as to release the tip of the lock of hair and the curled lock of hair is then slid longitudinally off the body I, as the resilient member 4 yields sufficient to enable this to be done very easily. The hair is wound around tube I and clamp I0 with sulcient looseness so that the clamp I0 can be moved to release the tip of the curled lock of hair.

In the embodiment shown in Fig. 5, the cap 2 is integral with an external flange 2a. In this embodiment the outer bar 4 has a U-shaped portion 4a which closely surrounds a portion of the flange 2a. Otherwise the parts are the same as those previously described. The flange 2a confines the curled lock of hair H so that it cannot slip over the outer wall of the cap 2.

The embodiment of Figs. 6-8 eliminates the spring I. In this embodiment, the ferrule 3 is provided with a longitudinal extension I3. This extension I3 is provided with radial teeth, as clearly shown in Fig. 8. The ferrule 3 has the same tight or drive fit on shank 5, as in the previous embodiment. Hence, while the ferrule 3 can be detached longitudinally from the inner shank 5 byusing suilicient force, the ferrule 3 and the shank 5 are connected so that shank 5 is held against turning when ferrule 3 is held against turning.

A sleeve I5 is located at the tip of the tube I and this sleeve I5 has a flange which abuts the inwardly-turned end wall of the narrow end of the tube or mandrel I. An outer sleeve I4 has a head or flange which abuts the inwardlyturned end wall of the tube I. 'I'he adjacent longitudinal wall-portions of the members I4 and I5 have a tight or drive fit. The inner longitudinal wall of the sleeve I4 has teeth which mesh with the teeth of the extension I3. 'Ihe holding bar 4, 5 is longitudinally movable relative to the body I, in unison with ferrule 3.

In order to assemble the parts, the members I4 and I5 are located and connected to each other and connected to the tip of mandrel I, while the cap 2 is displaced from the larger end of the mandrel I. This can be easily done by means of suitable assembly tools. The shank 5 and the cap 2 are then assembled with the body I and with the ferrule 3.

When the holding member 4, 5 is in the fullline position shown in Fig. 6, the teeth of the member I3 mesh with the teeth of the member I4, so that the cap 2 and the body AI cannot turn relative to the ferrule 3 or relative to the holding member 4, 5. When the shank 5 is moved to the broken-line position shown in Fig. 6, the extension I3 is pushed out of the sleeve or eyelet I4. Then, if the operator holds the ferrule 3 with one hand, the cap 2 and the body Loan be turned in unison freely with the other hand, while the members 4 and 5 are held against turning by ferrule 3. Therefore the lock of hair H can be Wound up as previously stated. After the lock of hair has curled, the extension I3 is pushed into the eyelet I4, thus holding the mandrel I against backward turning movement. The operation of the second embodiment is therefore the same as the operation of the first embodiment, save that the second embodiment omits the spring and uses two intermeshing members in place of the spring.

The various parts can be made of any suitable metal or other material.

This curler is the rst of this particular type which has eliminated a pivoted holding band for preventing the curler from turning backwards so as to unwind the hair.

The invention is not necessarily limited to the use of a ferrule or finger member, because the shank 5 and the inner wall of the mandrel I can be provided with any suitable bearing means. Hence whenever I refer to a finger member for the shank 5 in a claim or claims, I include a projection of the member 5 or any means whereby the member 5 can be held stationary while the mandrel I is turned relative thereto. The direction in which the mandrel I is turned relative to the shank 5, in order to wind up the curl of hair, may be designated as the forward direction. The spring I permits the mandrel I to turn forwardly, if moderate force is used. The spring 1 and the washer 8 and the collar 6a constitute means for preventing the mandrel I from turning backwards relative to the shank 5. y

In order to avoid limiting the invention to the use of the washer 8, said washer 8 may be considered as forming a part of the Wall of the cap 2, against which one end of the holding spring 'I abuts. While the holding member and the mandrel can be separated by using suitable tools or suitable force, the assembly between the parts is permanent for the purposes of the invention. That is, during the use of the device, the holding device and the mandrel lI are maintained in predetermined relation. y

I have shown preferred embodiments of my invention, but it is clear that numerouschanges and omissions can be made without departing from its spirit.
